3D Tilt Card Option Selector

Premium selectable cards that tilt in 3D toward your cursor like they're mounted on gimbals, with a glare sheen that sweeps across the surface as they rotate. Checking a card locks in an accent edge-light. The selector pattern for GPU tiers, game difficulty and portfolio picks.

      opt.addEventListener('pointermove', (e) => {
        const r = card.getBoundingClientRect();
        const px = (e.clientX - r.left) / r.width - .5, py = (e.clientY - r.top) / r.height - .5;
        card.style.setProperty('--ry', (px * MAX_TILT * 2).toFixed(2) + 'deg');
        card.style.setProperty('--rx', (-py * MAX_TILT * 2).toFixed(2) + 'deg');
        card.style.setProperty('--gx', (px * GLARE_SWEEP).toFixed(1) + 'px');
        card.style.setProperty('--go', '1');
      }, { passive: true });
      opt.addEventListener('pointerleave', () => {
        card.style.setProperty('--rx', '0deg'); card.style.setProperty('--ry', '0deg');
        card.style.setProperty('--gx', '0px'); card.style.setProperty('--go', '0');
      });
    });
  };
  document.readyState === 'loading' ? document.addEventListener('DOMContentLoaded', init) : init();
})();
```

How this works

Each card sits in a perspective container and rotates via rotateX/rotateY read from --rx/--ry custom properties; a compact pointer handler converts cursor position into ±10° and writes the custom properties (CSS renders, JS only measures). The glare is a ::before linear gradient offset by --gx — a pixel value the same handler derives from the cursor — so highlight and tilt agree physically. Note the unit discipline: rotation vars are deg, the glare offset is px; CSS can't convert an angle into a length inside calc(), so the JS supplies each in its native unit.

The radio semantics are untouched: cards are labels over hidden inputs in a fieldset, arrow keys move selection, and the checked card gets an accent border + lifted shadow that works even with JS disabled — the tilt is pure garnish.

Make it yours

  • MAX_TILT constant caps the rotation; 4° is subtle, 12° is showy.
  • Glare intensity = the gradient's white alpha in ::before; sweep distance = the GLARE_SWEEP px constant.
  • Accent for the checked edge-light is --accent.
  • The specs rows are plain markup — extend freely.

Gotchas — read before shipping

  • Set perspective on the parent, not the card, or each card gets its own vanishing point and the row looks broken.
  • Never feed an angle var into a length slot — translateX(calc(var(--ry) * 6)) is invalid and silently kills the whole transform; keep deg and px vars separate.
  • Reset --rx/--ry on pointerleave with a transition so cards settle softly instead of snapping.
  • Skip tilt entirely under prefers-reduced-motion — the JS checks the media query once.

Floor set by :has(), oklch(), color-mix() as this demo is written. The core technique itself goes back further — Chrome 105+.

transform-style/perspective are ancient and safe; :has() handles checked styling. No-JS = no tilt, everything else intact.
